Create a Great Aquarium With Petco

Whether it’s a small bowl or a massive tank, there’s nothing quite like a well-kept aquarium to brighten up your home. Here at Petco in Santee, we want to ensure that you have the supplies you need to keep your fish happy and healthy.

Your One-stop Shop

One of the advantages of aquariums is that they are perfect both for beginning pet parents and for experienced hobbyists. Whether you’re interested in setting up a large saltwater reef tank, a smaller community aquarium or a desktop betta bowl, we can help you find the equipment, supplies and fish that you’re looking for. Petco provides a single convenient place for you to find everything aquarium related.

A Home for Your Fish

We offer a wide variety of homes for your aquatic pets, ranging from smaller fish bowls to much larger tanks. Our selection includes all-glass aquariums and acrylic aquariums as well as a wide variety of configurations. We have fish tank sizes ranging from half of a gallon to 75 gallons so that you’ll be able to find the perfect volume for your space.

In addition, we have a variety of accessories for fish tanks such as tank stands, lighting, hoods, chillers, heaters, thermometers, pumps and filtration and aeration systems that will make the aquarium a welcoming place for its inhabitants.

Live Fish

Of course, you can’t have an aquarium without any fish—and a few finned friends are the perfect addition to your home. It is best to purchase fish at your local Santee pet store, so that you can see the fish before you buy them and make sure they are in good health. Petco is an excellent choice if you’re looking for new pets, since we have locations across the country offering dozens of kinds of colorful live fish. Whether you’re looking for a single fish or an entire school, we carry a wide variety of pets you can add to your family.

Beautiful Bettas

Our selection of bettas is one of the largest you’ll find anywhere. These beautiful little fish are famous for their bright colors and intricate fins, but they are also an excellent choice for beginning pet parents since they require very little space and maintenance.

Freshwater Pets

If you’re looking for other colorful freshwater aquarium fish, we have a wide range of other creatures that make excellent additions to your tank. Some of the many species we have available include:

Calico, fantail and feeder goldfish

GloFish

Chinese algae eaters

Plecostomus

Neon, serape and red eye tetras

Mollies

African and South American cichlids

Platies

Danio zebra fish

Some of these fish do well in larger schools, while others should be kept in smaller groups. We’ll be able to help you find the right mix of fish for your aquarium.

Saltwater Fish

More experienced aquarium keepers might want to try their hand with a saltwater aquarium. Petco is unique among pet store chains in that we carry a wide variety of saltwater options in addition to our freshwater ones. Our stores have many different types of saltwater aquarium fish, including:

Butterfly fish

Clown and damsel fish

Lionfish

Boxfish

Tangs

Stingrays

Seahorses

Invertebrates and Other Creatures

A fish tank can contain more than just fish. Both invertebrates and non-fish vertebrates can be a good addition to your aquatic community. We carry freshwater and saltwater creatures such as anemones, maxima clams, crabs, snails and even frogs.

Live Plants

A live aquarium plant is one of the most popular items to add to a tank, and we have a great selection of plants. Not only do they help filter the water in the tank, they also offer a highly naturalistic environment for your pets to live in. We offer a range of plant species as well as substrate, fertilizers, lighting and everything else you need to keep your plants healthy.

Aquacultured Corals

If you’re looking for something a little more exotic than a plant, live corals are an excellent option. We carry a range of corals that are great for beginning and expert aquarium keepers in a variety of shapes and sizes. All of our corals are 100% aquacultured.

At Petco, we are strongly committed to protecting marine life, which is why we sell aquacultured organisms. These are creatures that have been raised in aquarium environments instead of being collected from the wild. Over 95% of our aquatic life, including all of our coral and most of our live fish, is raised in captivity, allowing you to enjoy your fish tank without having to worry about impacts on the environment.

Supplies and Equipment

We also offer a wide range of aquarium supplies so that you’ll have everything you need to keep your fish happy and healthy. Our equipment and materials include medications, supplements and a wide range of foods. You can also pick up all the water treatment supplies you need, such as algaecides, water conditioners and even salt mixtures for brackish and marine tanks.

Accessories

Make your tank look great! We offer tank backgrounds and a variety of gravels and substrates that can provide a cohesive look in addition to a wide variety of tank décor. Whether you want to create a sunken ship or Asian landscape, we have the ornaments you need.

Hard-to-Find Items

If you’re looking for something that isn’t available at your local Santee Petco location, we have endless aisles online featuring every product that our chain has to offer. We have literally thousands of items that can help pet parents keep their aquariums running smoothly, whether you have a 50-gallon tank or a small betta bowl.

Even if we don’t have what you want, we can help you find it. For items that aren’t commonly carried in our stores, our store partners can place special orders online to help you find what you’re looking for. If you’re shopping online for marine life, we have teamed up with LiveAquaria.com to give you access to hundreds of types of fish and other creatures.

How to Clean a Fish Tank:

Once you have set up your aquarium, it is important to keep the tank clean. When cleaning a fish tank, first remove the fish and place them into a smaller container. Remove all decorations and gravel and rinse them in clean water, then clean the sides of the aquarium with a sponge. Scoop out about half of the water in the tank and replace it with new water that is the same temperature. Then, return the decorations and fish to the tank.
